Optimizing Cutting for Less Waste

What Is Dynamic Optimization™?

Dynamic Optimization™ software from TigerStop®, also known as linear nesting, is an instant and mathematically precise way of deciding what order to process parts to optimize material yield. 

Does Order Matter?

YES!

The order in which you cut your parts from your stock material can have a dramatic effect on your overall material yield.

Consider this example: I am making a frame out of square stock, basically a rectangle box. I want to make it 5.5 ft. wide and 1 foot high. So I need 4- 5.5 ft. pieces and 8- 1 ft. pieces to complete the frame. My stock comes in 10 ft. lengths. Let’s look at the ways to lay this out.

I could follow the list exactly, which would leave me with 3- 10 ft. lengths of stock used and 11 ft. of waste.

Or I could optimize my material like the below example. Here I use 2 pieces of stock and have only 1 ft. of waste.

TigerStop’s Dynamic Optimization software will quickly figure out the best order to cut your parts so you always get the best material yield.

 

How Does This Help My Business?

  • Dynamic Optimization software determines the best use of material, so the operator (unskilled worker or pro fabricator) only has to focus on feeding parts and cutting.
  • TigerStop moves to the correct position up to .004” so the operator never has to use a tape measure or set a manual stop ever again.
  • TigerStop reduces station setup time between different cut lengths and allows the operator to optimize for defects like forklift stabs, shipping damage, dents, or aesthetic blemishes, while getting optimal yield.
  • TigerStop increases accuracy. The operator doesn’t have to worry about cutting errors or the associated costs of rework. Quality control concerns are no longer a bottleneck.
  • Dynamic Optimization reduces scrap waste and shelving costs. Purchase less raw footage while sending fewer pounds back to the recycler.
  • A TigerStop Dynamic Optimization station can even be used by an unskilled worker. Top paid fabricators and skilled workers can better use their time managing the shop or doing work requiring greater expertise.

 

How Does it Work?

Here we run through the process on an upcut saw. You can use Dynamic Optimization with many other applications as well. 

First, the operator enters his cutlist into the TigerStop. He can do this manually or using the TigerLink 6 downloading upgrade. Then he presses the done button. optimizing cutting TigerStop

The Operator enters a cut list and the material length and the Dynamic Optimization software will determine which part to cut first to give him the least amount of waste. The operator then simply makes the cut and the stop moves to the next position. He doesn't need to do any complicated math or cut in order of largest material to shortest.

When using Dynamic Optimization on a backboard fence as pictured below, the operator can also defect parts, that is, remove imperfections and flaws and get the best yield out of the remaining stock. This process is called Backboard Defecting

If there’s an aesthetic defect in his material or a forklift stab he simply enters the distance from the trim cut to his first defect. TigerStop’s Dynamic Optimization will use its proprietary algorithms to find the best yield of the material with the least amount of waste, and move to the correct position.

The operator feeds stock to the TigerStop. When the operator reaches the first defect he cuts it out and enters the next usable clear length. He continues to make cuts until stock completion, only moving material and cycling the saw. He repeats until TigerStop indicates the job is done.
